ROGER? 55a United States Patent 2,845,684 PREFABRICATED FoRM WITH SILLMEMBER Robert Bell, Detroit, Mich, 'assignor to Rockwall Company,Detroit, Mich., a corporation of Michigan ApplicationAligust 16, 1954,Serial No. 450,084

Claims. 01. 25-131 This invention relates generally to prefabricatedforms for composition walls having an ofiset portion or sill and refersmore particularly to improved means for forming the offset or sill.

It is an object of this invention to provide offset or sill formingmeans capable of being readily attached to and removed from the innerface of wall forming panels by fastening devices'which not only permitappreciable adjustment of the sill forming means relative to theadjacent wall forming pancl but, in addition, are shielded or protectedfrom the composition material employed in forming the wall.

The foregoing as well as other objects will be made more apparent as'this description proceeds especially when considered in connection withthe accompanying drawings wherein:

Figure 1 is a vertical sectional view through a'prefabricated form forcomposition walls;

Figure 2 is an elevational view of the outer side of the form shown inFigure 1;

Figure 3 is a sectional view taken on the line 3-3 of Figure 2;

Figure 4 is a sectional view taken on the line 4-4 of Figure 3; and

Figure 5 is a sectional view taken on the line 55 of Figure 4.

In the drawings, the numeral 10 designates a prefabricated form forwalls of composition material such, for example, as concrete and thenumeral 11 designates a form for producing a sill on the wall cast inthe'form 10. The form 10 comprises an inner wall section 12 and an outerwall section 13 held in lateral spaced relationship to the inner wallsection 12 by any suitable means such as tie rods 14. Each wall sectionhas a frame structure 15 and a panel 16 secured to the frame structureat the inner side of the latter. The panels 16 provide the wall sectionswith smooth inner surfaces which cooperate with one another to formopposite sides of a composition wall 17.

The tie rods 14 extend through aligned openings in the panels 16 and theopposite ends of the rods are removably anchored to the frame structure15 of the sections by wedges 18. The wedges 18 extend downwardly throughslots formed in the tie rods 14 and have portions at the upper endsshaped to hook over adjacent bars of the frame structure. Thearrangement is such that the rods 14 may be readily installed duringassembly of the form and may be easily removed by withdrawing the samefrom the wall 17 after the latter has partially set.

In the present instance it is desired to form a sill or ledge 19 on theouter surface of the wall 17 and this is accomplished by the form 11.The form 11 comprises a box 20 elongated in the direction of length ofthe wall sections and positioned within the space provided between thepanels 16 at the top of said space. The outer side of the box 20 is openand the box is clamped to the inner surface of the outer panel 16 withthe open side closed by the outer panel. The box 20 Patented Aug. 5,1958 has an inner wall in the form of a smoothirnperforate panel 21, abottom wall 22, a top wall 23, and end walls 24. In addition, the box 20has atleast one cross brace 25 extending between the top and bottomwalls intermediate the end walls 24. In any case, the box 20 cooperateswith the panel 16 of the outer wall section 13 to provide an enclosedspace 26 of a nature to exclude the composition material during thepouring operation. Also, the depth and height of the box 20 ispredetermined to provide the specified sill or ledge 19 on of the wall17.

The box 20 is removably clamped with its open outer parallel to theplane of the open outer side of the box.

The flange 29 is also spaced laterally inwardly frolnthe open side ofthe box and is fashioned with a vertically extending slot 31. The slot31 extends for the full length of the flange 29 intermediate oppositeside edges of the latter.

The opposite ends of the flange 29 are provided with tabs 32 whichextend laterally inwardly from the flange 29 and are welded to theflange 28. The tabs 32 are formed with elongated slots 33 which formextensions of opposite ends of the slot 31 in the flange 29. Also thefastening device 27 is strengthened by a reinforcing plate 34 extendingbetween the tabs 32 and welded to the latter'in opposed relationship tothe flange 28.

-In addition, the fastening device 27 has a bolt 35 flattened at theinner end as at 36 to freely extend through the slot 31 in the flange 29of its anchoring element 27, and has pin 37 extending at right angles tothe bolt 35 through an opening in the flattened end 36 of the bolt. Theopposite ends of the pin 37 have a rolling contact with the innersurface of the flange 29 at opposite sides of the slot 31 and therebypermits swinging movement of the bolt 35 relative to the flange 29 in aplane perpendicular to a plane including the flange 29. Also, the bolt35 may slide freely relative to the flange 29 to different verticalpositions (Figures 4 and 5) and may also slide along the slots 33 in thetabs 32 at opposite ends of the flange 29. As will be apparent from thedrawings sliding of the bolt 35 vertically along the slot 31 in theflange 29 permits adjusting the elevation of the box 20 relative to theouter wall section 13 to locate the sill or ledge 19 in the specifiedposition, and sliding of the bolt 35 along either of the slots 33 in thetabs 32 renders it possible to locate the bolt in an out-of-thewayposition when the box is not in use.

The outer end of the bolt 35 projects through an opening 38 formed inthe panel 16 of the outer wall section 13 and also through an openingprovided in one flange of an angle plate 39. The angle plate 39 issecured to the outer side of the panel 16 for the outer wall section 13and is also fastened to an adjacent part of the frame structure 15, asshown in Figure 3 of the drawings. This angle plate may be omitted, ifdesired, but is preferred in cases where the wall section 13 is formedprincipally of wood or some equivalent material. In any case, the outerend of the bolt 35 is formed with a slot 40 therethrough which extendslengthwise of the bolt and receives a wedge 41. The wedge 41 is in theform of a flat plate having the opposite edges converging tosubstantially a point and having the upper end turned laterally toprovide a head 42. Actually the inner edge of the wedge 41 the outersurface is perpendicular to have a flat bearing contact with theadjacent flange of the plate 39 and the outer edge is tapered toward theinner edge to have a wedging engagement with the bolt 35 at the outerend of the slot 40.

The above structure is such that downward movement of the wedge 41relative to the bolt 35 forces the open side of the box 20 tightlyagainst the panel 16 of the outer wall section 13. As stated above thebolt 35 is adjustable vertically relative to the box 20 so that the boxmay be readily positioned at the proper elevation on the panel 16 of theouter wall section 13 before driving the wedge 41 in place. As alsonoted above, the fastening device 27 is housed entirely within the panel21 and walls of the box 20 and is thoroughly protected from thecomposition material during the pouring operation.
